application led January 21, glfl. Serial No. 813,403.

o all whom 'it' 'm ay concern Be it lrnewn that l, Go'rrnon limoen, of itochester, in the county` et Monroe and State of New' York, have invented certain new and useful inrw reinents in Drying spparatns; and l do hereby declare the 'tpl- .lowing to a uilj, clear, and exact description ot the same, reference being had to the accompanying drawings, forming a part ot' this specification, and to the reference-numerals marked thereon.

My invention has for its object to provide an improved construction for drying apparatusy of the general type embodying a rotary reticnlate cylinder' for containing the material or articles to be dried, and a heating means together with a v4fan, blower or other current producing medium for carrying air i'irst into intimate relation with the heating means and thereafter through the drying cylinder or tumbler, and one of the chier' purposes oi my improvement is to .afford a simple construction in which the diterent parts are readily accessible.

Another object or" the invention resides in reducing the costof operation of the machine by making a more advantageous use of the heating means, that is to say, by utiliztne maximum extent the heated air ing to before it dischareed from the machine. In .this manner the eiiitiency of the apparatus is censiderahly increased and the cost of operation is greatly diminished by lessening the required aineunt of heating medium for a given amount of work performed.

To these and other ends the invention consists in certain. improvements and combinations of part. ali as will be hereinafter more fully described, l e novel features being pointed out in thc claims at the end of the specification.

ln the drawings: Figure l is a View in end elevation ci a machine embodying a preferred arrangement oi my invention; Fig. 2 is an end elevation looking in the opposite direction; Fig. 3 is a View in front elevation, with parts in section; Fig. Li is a transverse vertical sectional View. and Fig. 5 is a sectional View on the iine :3k-5a of Fig. 4.

Similar reference characters throughout the several igurcs indicate the same parts,

My invention is susceptible of various applications. and in the present embodiment, l have shown it as applied to a machine for drying article-.1 o? clothing for laundry uw,

and according to a preferred arrangement,

A designates agcasing which may be of any suitable form and 1s provided` interiorly with the drying chamber B within which is contained the rotatable cylinder or tumbler C mounted in suitable bearings at the ends of the casing and adapted to be operated in any convenient manner.

Arranged at the rear part of the casing is a heating chamber D Within which are arranged a series of heating coils E adapted to be supplied with steam or other heating medium. The heating chamber is extended upwardly toward the top of the casing forming a passage F which communicates With the opening G leading into the heating chamber, and thus carries the heated air to the top of the tumbler, whence it is disranged beneath the drying chamber at the forward part of the casing and acting to draw in a supply of fresh air continually and discharge it rearwardly through the outlet l from which lit passes into the heating chamber and upwardly to the top of the drying chambcr,. and then down through the tumbler. The fresh air supply may be obtained in any convenient manner and in the present ar angement, there are provided a series of opchingsJ arranged in the hinged door K which is provided at the lower part of the casing to permit access within that portion thereof.

L designates a screening chamber Within which is arranged one or more screening elcmcnts. ln the present instance, II employ two screens, indicated at L2. and L respectively and arranged at an angle to the perpendicular as shown in Fig. 4'. Disposed between the screening chamber and thc heating chamber is au exit chamber M which is separated from the heating chamber by a wall N having a comparatively wide opening (l at the bottom thereof. and preferably coextcnsive lengthwise with the separating walb Theupper portion of the exit chamber N is sepa rated from the screening chamber by a wall l which is provided with incomparatively narrow opening Q establishing communication between the screening chamber and the exit chamber Whenthe parts are normal or working position as shown in Figui'. "fj 'H R designates a door which is hinged to the casing and may be opened to empty and recharge the tumbler, when the d oor 1s opened, it is desirable to provide means ,for preventing an outrush'of heated air into the face of the operator. To this end, I- provide' ymeans for shutting oli cgmmunication between the air 'circulating-device 'and the heating chamberwhen desirable, which means preferablyxconsists of a gate or door S fixed upon a rock shaft S', and adapted to Y bel moved from the normal operative position shown in full vlines in Fig. 4, to the posis sition shown in dotted lines, so as to close the opening O. In order-to accomplish the operation of the door S, the rock shaft S' is, provided with an arm S2 to which is pivoted a lever S movable in a guide S4, from the position shown in full lines in Fig.' 1 to the position shown in dotted lines.

The lever Si carries a suitable 'handle vand 4 can be readily moved to either position, its

weight being-sufficient to hold the rock shaft either extreme position after it is once operated. With this construction, when the .operator desires toopen the door R, he first operates the-.lever S8 to remove the door S downu'fardly until it closes vthe opening O, so that further circulation into the heating chamber isprevented, and when the door R isA openedflll'ldcr these conditions, there is practically-n0 circulation through the dryfing chamb ,and hence no tendency for the heated coii v tofrush outwardly into the face of the operator. v

-T designates the-exhaust, or outlet to the atmosphere, "for thej more heavily moisture laden air,'the same being arranged at one end of the exit chamber M. AlVith the parts inthe-"normal pbsitionappearing in F ig. 4, air-is'taken in at. he openings J and carried intothe; ends of the fans H, of which there .are.preierably two, in the manner shown in Fig. 3, and discharged through the openings I into'the. screening chamber, Where itpasses through the screens L2 and L, removingall 'lintand dustgbeforc issuing into .the heatirigchamberif- The air-'is then forced upvmirfdlyto the-topA of the heating chamber, thence downwardly through the drying chamber and tumbler, and again over the same course@ Aportion of the heated air passes into thecxit chamber through the opening Q and is vdischarged to the atmosphere at T,

andthe openings Q, and O are so proportioned that the major-portion o'f the heated air is kept in a continuous circulation While only a small portion is discharged through the exit chamber, its place to be taken by the fresh air that is drawn in through the openings J. The screening chamber L is proa having an opening therein, agate'pr c.

vided at one end with a door L4, to permit access to the inside, and the screens are relatter of the lint which collects rapidly. f

With the herein described arrangement, I provide a machine of greatly increased etli-i vn i'ovable to permit readily cleaning thelmas wel-l as the chamber, to free the ciency, owing to the fact that the heated ing temperature by using less steam or other heating medium in the heating chamber, and at'the same time to complete the drying operation in a smaller space of time.v
